A stand-alone (heat spreader only) K26 SOM can be used in your application when the environment is able to maintain the temperature of the key components below the specifications listed in Table 1.

However, one of the following cooling solutions can be introduced:

  • An off-the-shelf aluminum heat sink mounted to the heat spreader to extend the thermal performance.
  • The following figure shows an active heat sink to further extend the thermal performance (left) and a cooling plate to maximize the thermal performance (right).
Figure 2. Examples of Active or Cooling Plate Solutions

No matter the application, a thorough thermal model simulation must be conducted to ensure that the thermal solution is capable of maintaining the active components at temperatures below their rated temperatures. Also, if a thermal solution is added to the heat spreader, the appropriate thermal interface material (TIM) must be used.

Note: Avnet provides a thermal solution for the K26 SOM that attaches to the aluminum heat spreader, for more information see
